PFS7326H

PFS7326H Description

The PFS7326H is a Continuous Conduction Mode (CCM) Power Factor Correction (PFC) controller from the HiperPFS™ series, manufactured by Power Integrations. This IC is designed for power management applications and is housed in a Through Hole package, specifically a Tube. It operates within a supply voltage range of 10.2V to 13.2V, making it suitable for a variety of power supply designs. The PFS7326H is RoHS compliant and REACH unaffected, ensuring it meets environmental and regulatory standards. It is classified under HTSUS code 8542.39.0001 and has a Moisture Sensitivity Level (MSL) of 1, indicating it is not moisture sensitive and can be stored without limitations. Despite its Obsolete product status, the PFS7326H remains a robust choice for legacy systems and specific applications where its unique features are required.

PFS7326H Features

The PFS7326H offers several key features that distinguish it from other PFC controllers:

• Continuous Conduction Mode (CCM): This mode ensures efficient power delivery by maintaining a continuous current flow through the inductor, resulting in lower total harmonic distortion (THD) and improved power factor.
• Through Hole Mounting: The Through Hole package type provides a reliable and secure mounting solution, ideal for applications requiring robust mechanical stability.
• Wide Supply Voltage Range: The ability to operate within a 10.2V to 13.2V supply voltage range makes the PFS7326H versatile and adaptable to various power supply configurations.
• Environmental Compliance: Being RoHS compliant and REACH unaffected ensures that the PFS7326H meets stringent environmental regulations, making it suitable for global markets.
• Moisture Sensitivity Level (MSL) 1: The unlimited moisture sensitivity level means the device can be stored and handled without the need for special precautions, simplifying inventory management and reducing costs.

PFS7326H Applications

The PFS7326H is well-suited for a range of power management applications, including:

• Power Supplies: Ideal for AC-DC power supplies in consumer electronics, industrial equipment, and telecommunications infrastructure.
• Energy-Efficient Appliances: Enhances the efficiency of appliances by ensuring optimal power factor correction, reducing energy consumption and improving overall system performance.
• Lighting Systems: Suitable for high-intensity discharge (HID) lighting and LED lighting systems, where precise power control and high power factor are essential.
• Renewable Energy Systems: Can be used in inverters and converters for solar and wind energy systems, contributing to efficient power conversion and grid compatibility.
